2 Claims. 1

This invention relates to air-conditioning units,

and more particularly to an air conditioner which maybe built into the wall of a house.

It is an object of the present invention to provide a combined heating radiator and humidifier which can be contained within the wall of a room wherein the unit further contains fan elements for causing the circulation of the air through the .unit. i

It is another object of the present invention to provide in a combined heatingand humidifier unit an arrangement wherein water may be dropped or ejected with a fine spray on the surface of the radiator to humidify the air being circulated through the unit. 7 .7

It is another object of the, present invention to provide in a combined air-conditioning and heating unit a common drain for cooling water that may be sprayed over the radiator surface for cooling when the steam is turned off, the water being returned to the sewer system.

For other objec and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawings, in wlnfch:

Figure 1 is a front elevational view of theairconditioning unit with the door of the housing opened up to ShOWjhe interior of the housing therewithin. I Figure'Z is a longitudinal cross-sectional view taken on line 2-2 of Figure land looking in the t the arrows thereof. Figure 3 is a transverse cross-sectional view taken on line s 3 of Figure 1, and looking in the direction of the arrows thereof, and upon the fans disposed in the top of the housing.

I Figure 4 is a view showing a' math d oiapplying the air-conditioning heating and humidifying unit to steam and hot water radiators or heating systems now in use. p

Refcrringnow to the figures, Hi represents a housing or casing adapted to be disposed in a wall that its front portion will lie flush with the interior wall surface and so that no floor space is consumed. The housing may also be portable and adapted to be used as a separate complete unit. On this housingis a door ll adapted to swing on hinges l2 and is to the open position shown in Figured. Within this casing it is steam radiator gs having an inletpipe I5 and an outlet pipe Hi1 A steam main I! extends vertically through the wall and leads to the inlet for delivery oi steam to the steam radoor and adapted to lie in .tion of the driving motor 31.

diator 14. The inlet i5 is' controlled by alvalve l8. The inlet includes afunion l9. On the outlet !5 at the bottom of the radiator is a radiator trap 2! having a down pipe 22 connectedwith a radiator drain pipe 23. At the bottom of the housing is a pan 24 adapted to catch water which is sprayed over the radiator when the device is From this pan there is extended a trap 25 which is connected to a valve 25 to the same return 23 as is utilized for the condensation within the radiator. J Also extending upwardly throughjthe wall parallel to the pipe 11 is a cold water pipe 21 for connecting water to a laterally extendingspray pipe 28 within the housing. A valv e 29 controls the flow oiwater to the spray pipe 28.. The spray pipe has a plurality of openings adapted to spray water downwardly longitudinally spaced over the radiator M. This water forms a screen and the air which is caused topass upwardly over the radiator l4 will be cooled or moistened.

.The dead end of the spray pipe ZB is carried in a bracket 3! connected to one sideof the casing.

These fans are driven by amotor 3'! through drive chains 38. This motor 3! is also located at the top of the casing upon a'bracket 39 on the inner wall of the casing. v H v The motor 3Tiscontrol led by a thermostat 4| at times when the radiator I l-is being used for heating purposes. At other times when it is desired to use the unit for cool ng purposes, a toggle switch 42 is thrown to cause the constant rota- A supply cable 43 extends upwardly along the side of the casing for delivery of currentto thetoggle switch 42. Cables 44 connectbetween the toggle switch and the thermostat 4|. With the door ll closed and the fans 35 in operation, air will be drawn through the large opening 33 atithe bottom of the door and upwardly overthe radiator l4 and thence outwardly through the small openings '34 in the top of the door.
